L-Shaped Plot Area Formula
An L-shaped plot can be calculated by treating it as a larger rectangle with one rectangular corner section removed.
Outer Rectangle Area = Outer Length × Outer Width
Cut-Out Area = Cut-Out Length × Cut-Out Width
L-Shaped Area = Outer Rectangle Area − Cut-Out Area
The cut-out dimensions describe the rectangular section removed from one corner of the outer rectangle. The calculator checks that both cut-out dimensions are smaller than the corresponding outer dimensions.
How to Calculate an L-Shaped Land Plot
- Measure the full outer length of the plot.
- Measure the full outer width of the plot.
- Measure the length of the rectangular corner cut-out.
- Measure the width of the rectangular corner cut-out.
- Subtract the cut-out area from the outer rectangle area.
- Express the result in the required square-area unit.
Example: 10 m × 8 m Plot With a 4 m × 3 m Cut-Out
Suppose the outer rectangle measures 10 metres by 8 metres and a 4 metre by 3 metre rectangular section is removed from one corner.
Outer area = 10 × 8 = 80 m²
Cut-out area = 4 × 3 = 12 m²
L-shaped area = 80 − 12 = 68 m²
When to Use This Calculator
Use this calculator when the plot can be represented as an outer rectangle with one rectangular corner section removed. This includes many simple L-shaped or corner-shaped plots.
If the plot has a different irregular boundary, use the Irregular 4-Sided Plot Area Calculator when its geometry matches that calculator's measurement method.
Common Measurement Mistakes
- Mixing metres, feet, yards, or another length unit.
- Confusing linear measurements with square-area measurements.
- Measuring the cut-out from the wrong corner or boundary.
- Using a cut-out dimension that does not match the actual rectangular corner section.
- Assuming geometric area automatically represents an official revenue-record area.
Frequently Asked Questions
What is the formula for an L-shaped plot?
Calculate the outer rectangle area and subtract the area of the rectangular corner cut-out.
Can I calculate an L-shaped plot in square feet?
Yes. Enter the dimensions in feet and select square feet as the result unit, or use another supported length and area unit combination.
Does the cut-out have to be at a corner?
Yes. This calculator uses the specific geometry of an outer rectangle with a rectangular corner section removed.
Can this calculate any irregular plot?
No. It is intended for the specific L-shaped geometry described above. Other irregular boundaries require an appropriate geometric measurement method.
Land Measurement Note
This calculator provides a geometric area calculation based on the measurements entered by the user. It does not determine legal ownership, cadastral boundaries, survey boundaries, or official revenue-record area.
